This happened a long time ago....
A "friend" stopped by. My dog at that time was a Pit. He was a nice good dog, loved children, and was nice to everyone, except for one person.
Something clicked when that friend walked into the house, my dog wanted to attack him. I did stop him b4 he got his teeth into the friend. The friend wanted to borrow money, I went ahead and loaned it to him. Well, it turned out, that was the last time I ever saw that "friend."
So now, I live by these words....
